Abstract
The utility model discloses an anti-downdraft ventilator matched with a gas water heater, which is mainly composed of an air exhaust pipe and a chimney. The utility model the inside of the air exhaust pipe is provided with a device for blocking downdraft. The utility model has the advantages of artful design and reasonable structure; the gas water heater and the safety air exhaust problems are solved by the method except the gas water heater; the limitation of the existing like technique is broken; the objective laws that the development of any technique is from simple technique to the complicated technique and from complicated technique the simple technique.
Description
The utility model relates to a kind of and the matching used venting gas appliance of gas water-heater, particularly relates to the occluding device of down draught in this venting gas appliance.
Gas water-heater has extensively entered ordinary family, and it is comfortable and convenient to have brought to daily life.Yet the down draught problem of gas water-heater is but perplexing users all the time, even can cause taking place because of coal gas pours in down a chimney the incident of being poisoned to death.So become the problem that presses for solution.For this reason, released a kind of full-automatic gas-fired water heater of forced exhaust formula in the market.This product is the down draught phenomenon that takes place when preventing the water heater use, adopts the air exhauster forced exhaust, when still having down draught greatly as if wind-force, then relies on the device in the water heater to cut off combustion gas automatically, treats to refire after the wind.The problem and the defective of its existence are: A. cost height causes price to exceed common water heater 1/3rd to 1/2nd nearly.B. damage easily.Frequently cut off when wind is big, light, to be that gas water-heater is big avoid this situation.Though C. utilize the air exhauster forced exhaust, but still can't block down draught.D. can't solve the anti-down draught problem of existing other kind gas water-heater of user.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, can with the anti-down draught venting gas appliance of the matching used gas water-heater of existing all kinds gas water-heater.
The technical solution of the utility model is, a kind of gas water-heater is prevented the down draught venting gas appliance, mainly is made up of outlet pipe and chimney, and its characteristics are: the occluding device that is provided with a down draught in the outlet pipe.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, rational in infrastructure, solve the safe exhausting problem of gas water-heater by the approach beyond the gas water-heater, broken the limitation of existing similar technology, the development of having confirmed any technology all goes from the simple to the complex, again by numerous to the letter this objective law, the industrial utilization of tool height.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, the outlet side of outlet pipe 10 links to each other with chimney 20.Be provided with the occluding device 30 of a down draught in the outlet pipe 10.The occluding device 30 of down draught is one to offer the inclined-plane 32 of exhaust port 31, and the top on inclined-plane 32 is hung with one can be with exhaust port 31 complete closed, and that adopts that copper sheet makes is light, thin, very and heat-resisting check valve sheet 32.Wherein, the outlet side of outlet pipe 10 is provided with a choke face 40.When this device and the gas water-heater proper functioning of joining, when waste gas was discharged, it is vertical or preposition that check valve sheet becomes, and waste gas discharges by chimney from exhaust port.When down draught took place, air-flow toward returning back to top, closed exhaust port with check valve sheet, the blocking-up down draught.After the wind, check valve sheet is recovered normal working state under the effect of deadweight and exhaust flow power.Wherein, the choke face helps that down draught wind-force is more concentrated to be acted on check valve sheet and exhaust port is firmly sealed.
Claims (3)
1, the anti-down draught venting gas appliance of a kind of gas water-heater mainly is made up of outlet pipe and chimney, it is characterized in that: the occluding device that is provided with a down draught in the outlet pipe.
2, by the anti-down draught venting gas appliance of the described a kind of gas water-heater of claim 1, it is characterized in that: the occluding device of down draught is one to offer the inclined-plane of exhaust port, and the top on inclined-plane is hung with one can be with the check valve sheet of exhaust port complete closed.
